Autocorrect is fairly well understood and an LLM is an extension of that. (Yes, I know it's more complicated - still, it's a reasonable first approximation)
I wouldn't say that autocorrect and autocomplete are well understood by most users, but are well-accepted and not feared and/or fetishized. Telling my non-tech relatives and friends that "ChatGPT is extremely fancy autocomplete" has settled most of them down a bit.
While we're on the topic of stroking our epeens, do you know how horoscopes and astrology work? Most people here with that condescending attitude will never comprehend it either. FWIW, it's one of the topics I've been trying to understand and come up with a consistent theory for a while.
(Not to say those who believe in horoscopes and astrology know how it works though...)
There is no complete theory, because having a complete theory would require a complete theory about cognition. But the general understanding is that horoscopes and astrology play into the fallacy of personal validation. People are bad at evaluating how generic certain descriptions are. It is a well researched and replicated result. The arguments supporting horoscopes and astrology are also written in a way to make them impossible to disprove, making them unscientific.
